    摘要： An object of the present disclosure is to provide a thickener that can be suitably used as a thickener for adhesives and is excellent in long-term stability when it is used in the application of a thickener for adhesives, particularly when used in cyanoacrylate-based adhesives. A thickener contains a methacrylic resin having an Mw of 85,000 to 1,500,000, wherein η1 and η2 satisfy 1.0≤η2/η1≤5.0, where η1 is a viscosity (Pa·s) of a solution of the methacrylic resin in ethyl cyanoacrylate at 25° C., and η2 is the viscosity (Pa·s) of the solution at 25° C. after cooling when the solution is allowed to stand at 60° C. for 48 hours to cool to 25° C. (where the concentration of the methacrylic resin in the solution is 20 mass %, 10 mass %, or 7 mass %, depending on the Mw of the methacrylic resin).

    摘要： A reactive pressure-sensitive adhesive element that includes: i) a carrier layer; ii) a first adhesive layer arranged on a first surface of the carrier layer that comprises a first UV-curable pressure-sensitive adhesive; and iii) a second adhesive layer arranged on a second surface of the carrier layer facing away from the first surface, wherein the second adhesive layer comprises a second UV-curable pressure-sensitive adhesive. Each of the first and second UV-curable pressure-sensitive adhesives, based on a mass of the respective pressure-sensitive adhesive, comprises: x) one or more poly (meth) acrylate compounds in a combined mass fraction from 35% to 85%; y) one or more polymerizable epoxy compounds in a combined mass fraction from 10% to 50%; and z) one or more photoinitiators in a combined mass fraction from 0.1% to 5%. Further, the carrier layer comprises a foam carrier, the foam carrier comprising one or more polyolefins.

    摘要： Provided is a silicone adhesive composition and an application thereof, that has a viscosity that enables coating even with a small amount of solvent content, has excellent curability due to hydrosilylation reaction, cures, has sufficient adhesive strength for practical use, and has excellent mechanical strength and elongation of the adhesive layer after curing, and can form a pressure-sensitive adhesive layer having sufficient adhesive strength for practical use. The adhesive composition comprises: (A) a chain-like organopolysiloxane having at least two aliphatic unsaturated carbon-carbon bond-containing groups only at the terminals of the molecular chain; (B) a straight-chain organohydrogenpolysiloxane having silicon-bonded hydrogen atoms only at both terminals of the molecular chain; (C) a resinous organopolysiloxane; and (D) an organopolysiloxane having at least one or more aliphatic unsaturated carbon-carbon bond-containing groups at locations other than the ends of the molecular chain, and having three or more aliphatic unsaturated carbon-carbon bond groups in the molecule.

    摘要： Adhesive compositions for medical and non-medical uses are provided. The adhesive compositions can include cyclic disulfide monomers, oligomers of reactions between the cyclic disulfides, polymers of the cyclic disulfides, solid articles formed from the polymers, and any combination thereof. Methods of making, using, and recycling the adhesive compositions are provided, including use of the adhesive compositions on a variety of substrates that include biological tissue; biomaterials, including synthetics and natural such as bone, wood, and cellulosics; metals and alloys; polymers, plastics, and rubbers; ceramics; composites; and, any combination of these materials. The adhesives can adhere to substrates in a variety of environmental conditions that include ambient atmospheric conditions, wet conditions that include adhering materials underwater, and in a wide variety of temperatures and pressures, such as those temperatures and pressures found in medical environments, including in living tissue, as well as many residential, commercial, industrial, and manufacturing environments.
